"Jack" digital antenna

I have installed several of each. Mast mounted and roof level mounted. It is an excellent antenna. I am currently using the replacement head on my RV and just installed one on my friends RV. If you have the crank up antenna already then installing the replacement head is a ten minute job tops.

Bought a new TT and didn't have time to change the Batwing to the Jack antenna before first trip. Got to campground and could not receive any stations so as to be able to watch TV on the Batwing. Climbed up on the roof and changed over to the Jack antenna. I then got 5-6 stations clear and strong with NO break up of signal. I'd go with the Jack even though some report shows different on a bench test, real life use is what counts.

Nice article. I read Spectra so this is a good comparison. It would be nice to have one of those $20K Analyzers, wouldn't it? Yep, carrying around an extra 25 pounds and 2 cubic feet of space not to mention the power draw.

Oh, well. If someone can borrow one and analyze and publish, I say good on 'em.

It was $60k

OP: It's not a digital antenna, its just an agnostic antenna. Also, rule #1 in radio of any kind, and the hams here will back this up: There is NO substitution for height.

Getting the antenna away from the RV and all the noise generated within (like allot of LED's) can often make all the difference in reception. If you INSIST on installing a Jack, at least get one that can be mounted on the mast that you can get away from the coach and up in the air where where it belongs.

The following link shows a comparison of the Jack and Batwing. If you can read the spectrum analyzer results you can see the the Batwing really does outperform the Jack

To me the biggest down-side of the Jack is it is NOT designed for VHF stations, almost all major markets have at least one VHF station

I did. It's a nice part and seems to work well.
During this coming season I plan on using both the Batwing and the Jack and keeping track of the differences in reception between them.
